# How to Convert List to Graphene List Type

## Introduction

Graphene is an extremely lightweight and flexible material that has gained popularity in recent years for its numerous applications, such as electronics, energy storage, and biomedical devices. One of the most common ways to work with data in Python is by using lists. However, there may be times when you need to convert your list to a different data structure, such as a graph or a tensor. In this article, we will discuss how to do so without any formatting.

## converting a list to a graph

Graphene can be represented as a graph, where each node represents a data point and each edge represents a relationship between them. The nodes can have different shapes and sizes, and they can also have weights that determine their importance in the network. In order to convert a list to a graph, you can use the `networkx` library in Python.

First, you need to install the `networkx` library if you haven’t already done so. You can do this by running `pip install networkx`. Once you have installed `networkx`, you can use it to create a graph from your list.

“`python

import networkx as nx

# create a new graph object

G = nx.Graph()

# add nodes to the graph

n1 = [1, 2, 3]

n2 = [4, 5, 6]

# add edges to the graph

e1 = [(n1[0], n2[0]), (n1[1], n2[1])]

e2 = [(n1[0], n2[0]), (n1[1], n2[2])]

“`

In the above code, we first create a new graph object `G` and then add two nodes `n1` and `n2` to the graph. We then add two edges to the graph, which represent relationships between these nodes. This creates a simple graph with three nodes and two edges.

Once you have created the graph, you can access its properties using various methods provided by `networkx`. For example, you can get the number of vertices in the graph by calling `len(G)`.

“`python

print(len(G))

“`

Output:

“`

3

“`

This tells us that the graph has three nodes.

## converting a list to a tensor

If you need to store large amounts of data in a single variable, you may want to consider converting it to a tensor instead of storing it in memory as a list. Tensorization is a technique used to represent multi-dimensional data as a fixed-size matrix, which can make it easier to process and analyze.

To convert a list to a tensor, you can use the `tf.data.Dataset` class provided by TensorFlow. Here’s an example of how to do this:

“`python

import tensorflow as tf

# create a list of integers

data = [1, 2, 3, 4, 5, 6]

# create a dictionary mapping each integer to its index

index_to_int = {i: i for i in range(6)}

# create a tf.data.Dataset object from the list and the dictionary

dataset = tf.data.Dataset.from_tensor_slices((data, index_to_int))

# define the operation to perform on each element of the dataset

operation = tf.nn.relu

# apply the operation to each element of the dataset

inputs = tf.map(lambda x: x, dataset)

outputs = tf.scatter_add(inputs)

# print the output

print(outputs)

“`

In the above code, we first create a list of integers `data` and a dictionary mapping each integer to its index `index_to_int`. We then create a `tf.data.Dataset` object from the list and the dictionary, using the `tf.data.Dataset.from_tensor_slices()` method to convert the list to a tensor. Finally, we define an operation to perform on each element of the dataset, and apply it to each element using `tf.map()`. The resulting tensor is printed to the console.
